What term describes the process by which a dry region becomes drier, vegetation dies, and soil becomes prone to erosion?

• A. Desertification
• B. Drought
• C. Erosion
• D. Deforestation

Answer: (A)

Desertification describes the long-term degradation of drylands, where a region becomes drier, vegetation dies, and soils lose structure and become more prone to erosion. It combines climatic factors like reduced rainfall with human activities such as overgrazing, deforestation, and unsustainable farming, which strip away soil moisture, organic matter, and protective vegetation. With vegetation gone and soils weakened, erosion by wind and water accelerates, further reducing productivity and reinforcing the degraded state. Drought is a temporary lack of rainfall, not a lasting change in land health. Erosion is the process of soil being worn away, which can occur in many settings but doesn’t by itself describe the broader decline in land condition. Deforestation involves loss of forests and can contribute to desertification, but the term we’re after specifically defines the broader transformation of a dry region into a more desert-like, degraded landscape.
